HEATING STOVE.

Application filed October 29, 1924. Serial No. 746,658.

This invention relates to heating stoves of the hot air type and aims particularly to improve stoves of this type. This invention also aims to improve and simplify the construction of stoves generally.

Further aims and advantages of the invention appear in connection with the description of the stove shown in the accompanying drawings, wherein illustrating one embodiment of my invention,

Fig. 1 is a. front elevation of my improved stove; I

Fig. 2 is a side elevation thereof;

Fig. 3 is a vertical central sectional view from front to back taken on the line 3-3 of Fig. 1;

Fig. it: is a similar view from side to side taken on the line 44 of Fig. 2;

Fig. 5 is a horizontal sectional view through the fire pot taken on the line 5-5 of Fig. 3;

Fig. 6 is a horizontal sectional View through the ash pit taken on the line 6-6 of Figs. 1 and 3, and

Fig. 7 is a detail view of the improved manner of attaching the legs to the base.

In the embodiment of my invention shown in the drawings, the stove includes a heating unit comprising the ash pit 11, fire-box 12 and dome 13. The bottom pan 14- of the ash pit 11 is of substantially rectangular form, and fire-box 12 and dome 13 are preferably of substantially circular form.

Preferably the bottom pan 1 1 is dished and formed with a horizontal flange 15 on the four sides thereof. The side flanges (Fig. 6) preferably are of greater width than the front and back flanges to provide for openings 16 for the passage of cold air into the stove. The side edges of the bottom pan (Fig. l) are formed with a short perpendicular flange 17 extending above and below the plane of the flange 15, and the rear and front flanges 15 are formed with a downwardly turned rim 18.

The ash pit 11 supports the fire box 12 and (as shown in Figs. 3 and 4.) the top of the ash pit is formed with an opening within which is snugly fitted a reduced downwardly extending rim 19 on the bottom edge of the fire box 12. The lower edge of the fire box preferably is formed with a horizontal bearing surface adapted to rest upon the top of the ash pit 11 when the heating unit is as m led. Hangers 21 may depend from the top of the ash pit to support the grate bars 22 of any approved construction. The front of the ash pit may have a door 23, which preferably is provided with a draft regulator 24:.

The fire box 12 and dome 13 may be formed with the usual flanged seats in order to provide a separable yet smoke tight joint be tween them." The dome 13 is formed with a forwardly extending mouth closed by a hinged door 25. The fine 26 extends from the rear upper end of the dome as is usual in such stoves. The heating unit when assembled is of substantially circular form in cross section excepting the ash pit which is substantially rectangular.

The outer jacket preferably is formed of front and back panels 27, 28, side panels 29, and a top 30. The front, back and side panels may be secured together in any suitable manner, but in the construction shown, the front and back panels are formed along their side edges with rounded arcuate sections which overlap and are secured to the side panels by means of fastening means, such as screws 31 (see Fig. 2), thereby form-- ing neatly rounded corners for the jacket. The lower edges of the back and the front panel preferably are formed with an inward ly extending horizontally disposed flange 32 (see Fig. 3) which rests upon the horizontal flange 15 of the bottom pan 14: and is locked in place by a horizontally disposed flange 33 on the ash pit 11. Thus, the weight of the assembled heating unit on the flanges 32 of the panels holds the assembled jacket in place with substantial rigidity.

The side panels 29 (Fig. 1) may consist of three sections, the upper panel 29 preferably convexed, a lower concaved panel 29 and a canopy 29 secured to the lower edge of the upper panel. The upper panel may be secured to the front and back panels for support in any approved manner. The upper panel terminates some considerable distance above the bottom pan 14. The lowor panel is concaved and is formed with a downwardly projecting rim which fits within the upstanding flange 17 on the side flanges 15 of the bottom pan 14. The ends of the. lower panel 29 may be secured to are uate edges of the front and back panels 27, 28 in much the same manner as the upper panel. The canopy 29 may be secured to the lower edge of th pp panel in any pappearance.

proved manner, and is adapted to cover or hide the upper edge of the lower panel and that portion of the fire box which otherwise would be exposed to view through the opening between the upper and lower panels. This construction of side panels permits of a highly ornamental jacket covering the heating unit- (Fig. 2) and at the same time affords two inlets for cold-air into the hea ing chamber between the heating unit and jacket; one through the opening between the canopy and lower panel and ash pit 11 through the openings 16.

The front panel 27 is cut away at the lower part to fitaround the ash pit door 23, and is also cutaway for a certain distancefrom the bottom to provide an inlet for the cold air into the stove. The front ing. The front panel is also formed with -an opening corresponding to the fire box door opening so that the panel may surround the mouth of the dome 13 at the fire box door.

The-back panel 28 (Fig. 3) is formed witha suitable grating near the bottom for the entrance of cold air into the space between the jacket and heating unit. an opening in the upper part of the back panel permits ofthe'insertion and removal of the water pan 36 (see Fig. 3), the outer surface of which forms a continuation of the back panel. A water pan door 37 seals the opening between the upper edge of the water pan and the back panel.

Provision is made for circulation of heated air and its escape from the stove, and in the embodiment shown in the drawings, the jacket cover or top 30 and the arcuate rim or beadon the upper edges of the front and side panels are formed as a grating. Preferably, this grating is formed to present a series of rows of diamond shaped openings, and the front panel, above the fire boi; door is similarly formed with agrating or openings.

: In practice, the several parts of the jacket and base frame are enameled or metal plated in order to present a pleasing and attractive The parts of the heating unit however, are not finished in this manner and heretofore it hasbeen difficult to conceal the unsightly unfinished outer edges of the bottom pan..

My invention contemplates the provision of an improved manner of attaching the supporting legs to the-bottom pan 14 to overcome this difficulty. In the structure shown in the drawings thesupporting leg 38-inay be of any desired shape or-design, and is preferably provided-with a horizontal lug 39 upon which the bottoinpan l l rests at la ting passage therebetween.

its four corners only, though it is to be understood that this feature of my invention is not confined to stoves having rectangular base, but applies equally well to stoves hav ing bases of any polygonal form. The legs may be rigidly secured to the bottom pan in any improved manner, as by bolts. The legs are formed with an upwardly extending lap or skirt e0 whichoverlaps and covers the unfinished corner edges of the bottom pan and the lower edge ofthe side panels. The usual base skirting 41 is suitably secured to the legs and is formed with similar lap or skirt 42-to cover and conceal the edge of the bottom pan and lower edge of the side panels between the legs.

To prevent the escape of smoke from around the fire box door .25, I have shown a cover member 43 secured to the door but spaced therefrom to provide an air circu- Ref Tring to Figs. 3 and 5, it will be apparent that the front panel 27 of the jacket is spaced from the mouth of the dome 13 to provide a communicating passage for the flow of air from the space between. Thus, a circulation of air is set up between the door and cover member 4-3 therefor. in communication with the passage. Smallamounts of smoke es caping from around the door willbe carried into the heating chamber and diffused with the air therein, before escaping from the stove.

My invention is susceptible of modifications in form and is not restricted to the exact construction shown and described.
